52. The law of conser­vation of mass states that mass can neither be created nor destroyed.

Meiosis

73. Meiosis is a type of cell division in which a necleus divides into four daughter nuclei each containing half the chromosome number of the parent necleus.
73. Meiosis consists of 8 phases, prophase 1, metaphase 1, anaphase 1 telophase 1, prophase 2, metaphase 2, anaphase 2, and telophase 2.
74. In prophase 1 homologous chromo­somes pair up and exchange fragments.
75. In metaphase 1 the chromasome pairs line up at the equator and attach to spindle fibers.
76. In anaphase 1 the spindle fibers pull the chromosome pairs apart.
77. In telophase 1 the spindle fibers pull the chromosome pairs into their own cells and form a necleus.
78. In prophase 2 both cells' homologous chromo­somes pair up and exchange fragments.
79. In metaphase 2 both cells' chromo­somes line up at the equator and have spindle fibers attach to them.
80. In anaphase 2 the spindle fibers in both cells pull the chromo­somes apart.
81. In telophase 2 the spindle fibers have pulled the chromo­somes apart and caused them to start forming their own necleus.

Elements, Molecules, and The Periodic Table

12. The periodic table has elements organized by the number of protrons each element has.
13. The number of protrons, neutrons, and electrons changes for each element.
14. Compounds can't be separated physic­ally.
15. Mixtures are 2 or more compound together.

Cell processes

35. Osmosis is when a liquid moves from an area of low concen­tration to an area of high concen­tra­tion.
36. Endocy­tosis is when a cell takes in matter and forms a vacuole.
37. Exocytosis is when a cell removes matter using a vacuole.
38. Photos­ynt­hesis is the process that plant cells use to make food.
39. Respir­ation is when a cell produces energy by taking oxygen and breaths out carbon dioxide.
40. Fission is when a cell divides into two.

Diseases

53. Leukemia is a disease that occurs when your body produces too many white blood cells.
54. Diabetes is a condition that occurs when your body can't process glucose normally.

Periodic Table

82. There are 10 types of elements, alkali metals, alkaline earth, transition metals, basic metals, semime­tals, nonmetals, halogens, noble gases, lantha­nides, and actinides.
83. There are 103 elements on the periodic table.
84. There are 3 categories of elements metals, metall­oids, and gases.
85. Hydrogen is the only gas on the left hand side of the periodic table.
86 You determine the atomic mass of a single atom of an element by adding up the mass of the protrons and neutrons.
87. The periodic table is arranged in periods or rows and they go from left to right. Each element in a period has the same energy levels.
88. The periodic table is also arranged in families or groups that go form top to bottom. Each element in a family has the same charac­ter­istics.
89. The charac­ter­istics of an element are also known as chemical properties which are things that allow a chemical change to occur.
90. Dmitri Mendeleev is the man that made the periodic table.

Physical and chemical changes

16. Chemical changes are also known as chemical reactions.
17. Chemical changes are different from physical changes because in a chemical change you can't get what was used in the reaction back but in a physical change, such as crumpling up a piece of paper, you can uncrumple the paper.
18. Chemical changes are charac­terized by the forming of a precip­itate, a substance formed by a solution.
19. A solution is a liquid mixture where a solute (the substance dissolved) is distri­buted evenly in the solvent (the substance that dissolved the solute).
20. Physical changes involve tearing or crumpling an object but while mainta­ining its original traits. Chemical changes involve changing the object through the use of chemicals.

Biotec­hnology

41. Biotec­hnology is the use of natural processes to create something.
42. Biotec­hnology is used in making better crops.
43. Biotec­hnology can also be used for making medicine.
44. Two biotec­hnology centers in North Carolina are located in Sanford, North Carolina and Research Triangle Park, North Carolina.
45. Biotec­hnology is also being used in the treatment of cancer.

Chemistry Vocabulary

64. Protrons are positively charged particles in the necleus of an atom.
65. Neutrons are particles with neutral charge in the necleus of an atom.
66. Electrons are negatively charged particles in the necleus of an atom.
67. A solution is a mixture of a solute and solvent.
68. A substance is made of more thanone element that combine to form something new, made from a chemical reaction.
69. A chemical reaction is a chemical reaction and when a new substance is made, bonds break and recombine to form something new.
